Research on Visualization Technology of Ocean Situation Based on OSG

In order to improve the image efficiency and human-computer interaction of 3D ocean situation display, on the basis of summarizing the lighting and dynamic display technologies of previous 3D ocean models, through the analysis of the requirements of ocean situation display and the software architecture mode combined with OSG/QT[1], technical methods such as sea surface fluctuation simulation based on FFT and volume rendering technology for cloud rendering are proposed, A more realistic ocean situation scene is realized. The above research results provide technical support for marine related situation software and build a real, intuitive and distinctive marine situation display effect.
